IPC: F21V3/04
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To enhance the initial visible light transmissivity of a photocatalyst film while suppressing the lowering of visible light transmissivity with time. SOLUTION: The photocatalyst structure is equipped with a substrate 1 having light permeability and the photocatalyst film 2 based on the coating film 2a containing titanium oxide as a main component formed on the surface of the substrate 1 and constituted so that transparent oxide 2b having a refractive index lower than that of titanium oxide is partially present on the outer surface of the coating film 2a.
